Can anyone recommend a good company that would be able to supply and fit an RNS510 unit and Bluetooth module?

Ideally a legit company and not someone who does it on the side.
Had a search round the web and fired a few emails off, but would prefer to use a company that's been recommended

Thanks
Chris
